Abstract

See full text

A method begins where a processing module segments data into data segments. On a data segment by data segment basis, the method continues with the processing module performing a decode threshold level of dispersed storage error encoding on a data segment to produce a set of decode threshold level encoded data slices and caching the set of decode threshold level encoded data slices. On a set by set basis, the method continues with the processing module performing a redundancy level of dispersed storage error encoding on the set of decode threshold level encoded data slices to produce a set of redundancy error coded data slices. The method continues with the processing module outputting at least one of at least some of a plurality of sets of decode threshold level encoded data slices and at least a corresponding some of a plurality of sets of redundancy error coded data slices.
